Meningococcal surge intensifies as South Australia records first death
South Australian died from invasive meningococcal serogroup B, the state's first death from the disease in 2026.
A young Adelaide resident died after being diagnosed with invasive meningococcal disease serogroup B in late October. South Australia recorded its first meningococcal death in 2026.
Cases have surged sharply across the state. There have been 22 cases so far in 2026, compared with 13 at the same point in 2025.
Of those 22 cases, 20 have been identified as serogroup B. The disease can progress rapidly and become life-threatening within hours if untreated. Early symptoms include fever, headache, vomiting, neck stiffness, sensitivity to light, and a distinctive rash of small red or purple spots.
Health authorities urge anyone with these symptoms to seek urgent medical attention immediately.
